To say something is “too much” or “too small” or that we drank “too much” and so forth, we use the verb
Adjectives
For i-adjectives we remove the い and add すぎる.
| Too high/expensive. |
And because it’s now treated as a verb we can use the te form; however, note that the object still requires the が particle.
| パソコンが |
| The computer was too expensive so I didn’t buy it. |
| Too scary. |
| The movie was too scary so I couldn’t watch until the end. |
For na-adjectives we just add すぎる without the auxiliary verb or な particle.
| Too complicated. |
| この |
| This maths problems is too complicated so I’ll ask the teacher tomorrow. |
Verbs
For verbs we need to use the verb stem.
| I drank too much yesterday—my head hurts! |
